The City of Cockburn has introduced stricter regulations for tree removal on private land, aiming to preserve mature trees and enhance the local urban canopy. The new tree planning policy, effective from May 28, 2026, mandates development approval for any 'tree damaging' activities on private property.
Key Changes in the Policy
Under the updated rules, protection now extends beyond trees listed on the significant tree register. The policy applies to trees that are 8 metres or taller, excluding palms and pest species. It also covers trees that must be retained or replaced when lost due to subdivisions or developments.
Development approval is required for activities such as tree removal, significant branch cutting, root damage, and paving or asphalting within the canopy drip line. However, routine pruning, removal of dead branches, and work to address immediate safety risks are exempt, though supporting evidence may be required.
Community Support and Background
Cockburn Mayor Logan Howlett stated that the policy responds to community demands for better protection of urban greenery. 'Big trees make a big difference to the lives of people and animals alike, and after our community asked us to act to protect them, we are doing just that,' he said.
The draft policy was publicly advertised over four months in 2025, receiving 323 submissions. Approximately three-quarters of respondents supported the new rules. 'Large, established trees are a defining feature of Cockburn’s neighbourhoods. They provide shade, help cool our suburbs, support local wildlife and contribute to the look and feel of our streets,' Mr Howlett added.
The policy is based on a model from the WA Local Government Association, with adjustments for clarity specific to the Cockburn community.
